OpenFOAM - Density/turbidity current

Density current over rough and uneven bottoms
We have implemented density/turbidity current solvers in OpenFOAM. Combined with the immersed boundary method, this solver can solve density/turbidity current over rough and uneven bottom. Our interest is to investigate the effect of bottom roughness on the development of the current.
A simplified version of the density current solver is the gravityCurrentFoam solver.
